Objective:To investigate the anatomical feasibility of the endoscopic transorbital approach (ETOA) to the orbital apex and lateral middle cranial fossa, to identify stable and recognizable surgical landmarks under endoscopic visualization, and to provide morphometric data for preoperative planning and intraoperative navigation.Methods:Stepwise anatomical dissection was performed on five formalin-fixed cadaveric heads and one fresh arterially injected cadaveric specimen to simulate the ETOA using a 0° endoscope. Key structures and their anatomical relationships were observed and recorded. Additionally, high-resolution CT scans of 50 adults were retrospectively analyzed. Three-dimensional reconstructions and measurements were performed using Mimics 17.0 software. Spatial validation was performed using 17 dry skulls to verify the consistency and reliability of osseous anatomical landmarks.Results:Cadaveric dissection identified the meningo-orbital band, superior orbital fissure, optic canal, foramen rotundum, and foramen ovale as reliable surgical landmarks for the ETOA. A topographic map of the surgical region was established based on the endoscopic view. CT measurements revealed the following distances (Mean±SD): the midpoint of the supraorbital rim to the foramen rotundum (57.31±3.59) mm and foramen ovale (71.46±3.42) mm; the lateral orbital rim to the lateral edge of the superior orbital fissure (37.38±2.52) mm; the distance from the superior orbital fissure to the optic canal (9.98±1.49) mm; and the distance from the anterior ethmoidal artery to the optic canal (19.98±2.05) mm. These measurements were consistent with dry skull data, indicating that these osseous landmarks had stable spatial relationships and were suitable for intraoperative localization.Conclusions:The ETOA provides favorable anatomical accessibility and clinical feasibility for lesions involving the orbital apex and lateral skull base. Key osseous structures demonstrate high identifiability and stable spatial relationships, serving as critical references for intraoperative navigation and preoperative pathway planning. The quantitative anatomical framework established in this study provides critical morphometric support for minimally invasive surgery targeting lesions in this region.

Objective To explore the effect of mirror therapy(MT)based on occupational therapy(OT)on alien hand syndrome(AHS). Methods From January,2022 to December,2023,20 AHS patients from the Affiliated Hospital of Xuzhou Medical Uni-versity were randomly divided into control group(n=10)and observation group(n=10).Both groups received conventional OT,while the observation group additionally received MT,30 minutes per session,twice a day,for four weeks.They were assessed with Wolf Motor Function Test(WMFT),Fugl-Meyer Assessment-Hand(FMA-H),and modified Barthel Index(MBI)before and after treatment. Results The scores of WMFT(t=5.771,P<0.001),FMA-H(t=7.875,P<0.001)and MBI(t=9.544,P<0.001)im-proved in the observation group after treatment,and they were better in the observation group than in the control group(t>3.129,P<0.01). Conclusion MT based on OT may improve hand motor control and activities of daily living in AHS patients.

Objective:To detect the expression of ARK5 in peripheral blood circulating tumor cells (CTCs) from pancreatic cancer patients and explore its correlation with the efficacy and prognosis for gemcitabine chemotherapy.Methods:A total of 175 peripheral blood samples of pancreatic cancer patients who were treated in the Department of Hepatobiliary Surgery, Second Affiliated Hospital of Jiaxing University from January 2016 to June 2021 were collected. CTCs were enriched by nano-microfluidic chip technology. The expression of ARK5 in CTCs was detected by immunofluorescence. According to the expression of ARK5, the patients were divided into two groups: positive group and negative group. The differences on clinicopathological features, the efficacy of chemotherapy, median survival and progression-free survival time between the two groups were compared.Results:CTCs were enriched in 98 of 175 patients (55.6%), including 70 ARK5 positive and 28 ARK5 negative patients. There were no significant differences on clinical features between the two groups, and the two groups were comparable. In the 70 ARK5 positive patients, 64 patients (91.4%) were resistant to gemcitabine, while only 12 of the 28 ARK5 negative patients (42.8%) were resistant to gemcitabine. The incidence of gemcitabine resistance in ARK5 positive patients was significantly higher than that in ARK5 negative patients, and the difference was statistically significant ( P<0.001). The median survival time was 11.5 months in ARK5 positive group and 14 months in ARK5 negative expression group, and the progression-free survival time was 6 months in ARK5 positive expression group and 8 months in negative expression group. The survival time of ARK5 positive group was significantly shorter than that of ARK5 negative group, and the difference was statistically significant ( P<0.05). Conclusions:The pancreatic cancer patients with ARK5 positive CTCs have significantly higher incidence of gemcitabine resistance and shorter survival time than those with ARK5 negative CTCs. Detection of ARK5 expression in CTCs may be a new method to judge chemotherapy efficacy and prognosis for pancreatic cancer patients.

We used the method of partial penectomy combined with penis lengthening to treat 2 cases of penile cancer. The penile lengths were lengthened by 3-4 cm. This method could retain the penis and sexual function to the maximum degree. And a few patients could avoid total penectomy and micturate on their feet. This operation is very simple and safe, with no complication.
